Comment (by chapoton):
Well, the issue is that of "order_ideal" is a synonym for "lower ideal"
and "order_filter" is a synonym for "upper_ideal". Before this patch,
everywhere one uses "order_ideal" and "order_filter". In my opinion, these
are bad names, and "lower ideal" and "upper ideal" are much better.
And, well, I think that "upper set" and "lower set" are '''very bad'''
too.
In any case, there is still some cleanup to do.
